Nickel/metal hydride (Ni/MH) battery is a secondary battery using hydrogen storage alloy for the negative electrode, Ni(OH)2 for the positive electrode, and alkaline solution for the electrolyte. Polypropylene nonwoven fabric is usually selected for the separator. The theoretical voltage is about 1.32 V, and the operating voltage is about 1.2 V which is almost the same as that of Ni/Cd battery [1]. The Ni/MH battery has been put to practical use for portable electric equipments in 1990 and for HEV (hybrid electric vehicle) in 1997 [2, 3]. 

After practical use, the energy density of the battery is doubled from 180 to 350 Wh/L by the development of the various technologies such as active material composition, surface treatment, and additives. This battery has been put to practical use for the power supply for the power tool by the improvement of the high output performance. The AA size and AAA size batteries that are compatible with a dry cell have been also put to practical use. This battery system has been put to practical use for HEV (hybrid electric vehicle) by the establishment of the battery management technology...

Lithium-ion batteries are being seriously considered for application in all-electric vehicles (EV) and hybrid electric vehicles (HEV s) because of their high power and energy densities [1, 2], The U.S. Department of... 

High-power lithium-ion batteries are promising alternatives to the nickel metal hydride batteries which are currently used for energy storage in hybrid electric vehicles (HEVs). Currently, Li(Ni,Co)02-based materials are the most widely studied cathode materials for the high-power lithium-ion batteries [1-4]. Although Li(Ni,Co)02-based materials meet the initial power requirement for the HEY application, however, it has been reported that they... 

Besides fuel-cell (electric) vehicles (FCV), there are other vehicle concepts under development, which are also based on electric drives ranked by increasing battery involvement in the propulsion system, and thus extended battery driving range, these are hybrid-electric vehicles (HEV), plug-in hybrid-electric vehicles (PHEV) - which both incorporate an ICE - and, finally, pure battery-electric vehicles (BEV), without an ICE. While electric mobility in its broadest sense refers to all electric-drive vehicles, that is, vehicles with an electric-drive motor powered by batteries, a fuel cell, or a hybrid drive train, the focus in this chapter is on (primarily) battery-driven vehicles, i.e., BEV and PHEV, simply referred to as electric vehicles in the following. 

Figure 15.3 shows the number of hydrogen vehicle sales per year for each scenario, and compares this with the historical market penetration of gasoline hybrid-electric vehicles (HEVs) in the USA, with the HEV curves displaced by 12 years, to reflect hydrogen s later introduction into the market. Scenarios 1 and 2 are similar to the market introduction rate of gasoline hybrid vehicles in the United States, but... 

Hybrid-Electric Vehicle (HEV) A vehicle that is powered by two or more energy sources, one of which is electricity. HEVs may combine the engine and fuel system of a conventional vehicle with the batteries and electric motor of an electric vehicle in a single drive train.
